Do Jewellers Cloths damage watches?

Hi all

I'm talking about a cloth like the one in the image (Blitz Jewellery Cleaning and Polishing Cloth).

These sorts of cloths contain some sort of chemical which can remove tarnish from jewellery, watches, etc.

I live in Hong Kong where the high humidity causes some tarnish to appear on the cases of my 18k gold watches (makes them look like rose gold), and using this type of cloth brings back their natural shine.

I'm guessing these cloths remove some of the gold in the process? But I'm not sure.

So my question is: Do Jewellers Cloths damage watches? And if so, is there a generally accepted number of times they can be used per year?

Thanks for your advice.

I live in Singapore - tell me about humidity😀. No experience with Blitz. I use Town Talk (TT) cloth, made in UK, on all my watches, gold and steel. If you can find TT go for it as they have one pack for gold and another for silver/steel. It will only remove discolouration (reddish hue) from gold cases and gray off-colour from silver/steel. Just wiping will do you like using a microfibre cloth on your spectacles. Just remember - never wash your polishing cloths.
